Bio‐Inspired Structural Color Irises as Physical Unclonable Functions for Anti‐Counterfeiting

Advanced Science, EarlyView.
This work employs colloidal photonic crystals to create macro‐to‐micro scale PUF anti‐counterfeiting patterns. Integrated with iris recognition algorithms, it establishes a multi‐layered optical anti‐counterfeiting system based on structural color irises.

Superelastic Fire‐Safe Aerogel with Hierarchical Structures via Dual Templates Aided by Microbubble Engineering

Advanced Science, EarlyView.
Here, a dual‐template strategy (ice and bubble template) is used to prepare fire‐safe aerogels with hierarchical structures. When the foam expansion ratio exceeds the jamming transition value in the foam system, the aerogels demonstrate superelasticity and extreme shape adaptability.

In Situ Formation of Mechanically Interlocked Heterointerfaces with Ultrahigh Bonding Strength for Mg‐Based Multilayered Sheets

Advanced Science, EarlyView.
Crystal‐orientation controlled hot‐rolling strategy creates Mg‐Ta immiscible composites featuring mechanically interlocked in situ formed interfaces (80.5 MPa bond strength) and excellent tensile properties (340–395 MPa UTS). Systematic multiscale investigations reveal a serration‐size‐dependent bonding mechanism and a three‐stage interfacial evolution
